Oxygen is slightly negative and hydrogen is slightly positive. This is polarity, it is the reason for all of waters properties. Because of this water molecules around attract creating hydrogen bonds. This gives the water molecules the ability to stick together and have all of these properties. ]]> 2016-10-26 21:07:59 UTC https://padlet.com/cagagnon/rcq7rjv9g86/wish/133482288 22brandtcd https://padlet.com/cagagnon/rcq7rjv9g86/wish/133482303 Clearly, you can see that the ice is less dense than water because the molecules spread out, whereas liquid water molecules are free to move around and actually are much closer than in a solid state.]]> 2016-10-26 21:08:06 UTC https://padlet.com/cagagnon/rcq7rjv9g86/wish/133482303 22casazzak https://padlet.com/cagagnon/rcq7rjv9g86/wish/133482311 Water's formula is H2O, which is two hydrogen atoms with one oxygen atom.

Oxygen is slightly negatively charged and that the hydrogen are slightly positively charged, this is called polarity. Also hydrogen bonds are water molecules that can have the slightly positive hydrogen from one molecule attracted to the slightly negative oxygen on another.  If a substance is polar it will dissolve in water if not than it's not polar. It also dissolves by forming hydrogen bonds with the water. ]]> 2016-10-26 21:08:36 UTC https://padlet.com/cagagnon/rcq7rjv9g86/wish/133482385 22rafaelag https://padlet.com/cagagnon/rcq7rjv9g86/wish/133482406 2016-10-26 21:08:46 UTC https://padlet.com/cagagnon/rcq7rjv9g86/wish/133482406 22fernandezaj https://padlet.com/cagagnon/rcq7rjv9g86/wish/133482414 In water there are positives and negatives and this is called hydrogen bonds. Polarity is the key behind the properties of water.]]> 2016-10-26 21:08:48 UTC https://padlet.com/cagagnon/rcq7rjv9g86/wish/133482414 22daviesmm https://padlet.com/cagagnon/rcq7rjv9g86/wish/133482523 This is good example because when water freezes it becomes less dense than water so it floats on the water

The water molecules come together and stay on the surface, instead of breaking off into the air. Although things that are denser than water should sink, the surface tension keeps those items up. That is why bugs can land on water and not sink. ]]> 2016-10-26 21:15:16 UTC https://padlet.com/cagagnon/rcq7rjv9g86/wish/133483427 22leanose https://padlet.com/cagagnon/rcq7rjv9g86/wish/133483547 2016-10-26 21:16:06 UTC https://padlet.com/cagagnon/rcq7rjv9g86/wish/133483547 22sanchezc1 https://padlet.com/cagagnon/rcq7rjv9g86/wish/133483548 2016-10-26 21:16:07 UTC https://padlet.com/cagagnon/rcq7rjv9g86/wish/133483548 22sanchezc1 https://padlet.com/cagagnon/rcq7rjv9g86/wish/133483578 2016-10-26 21:16:19 UTC https://padlet.com/cagagnon/rcq7rjv9g86/wish/133483578 22sanchezc1 https://padlet.com/cagagnon/rcq7rjv9g86/wish/133483609 2016-10-26 21:16:32 UTC https://padlet.com/cagagnon/rcq7rjv9g86/wish/133483609 22antimojm https://padlet.com/cagagnon/rcq7rjv9g86/wish/133483685 water molecules can also attract particles with areas of electrical charges.]]> 2016-10-26 21:17:11 UTC https://padlet.com/cagagnon/rcq7rjv9g86/wish/133483685 22sanchezc1 https://padlet.com/cagagnon/rcq7rjv9g86/wish/133483796 Its staying in a shape
